Tooth Sensitivity

Tooth sensitivity occurs when external stimuli trigger the nerves. There is a sudden, sharp, shooting pain in one or more teeth, and sensitivity toward hot, cold, sweet, and spicy food items. It is caused by overzealous brushing, tooth grinding, and gingival diseases. It is treated by the dentist depending upon the condition and the treatment required by the tooth.
